Title: Partition-wall unit having individual panel elements fitted together edge to edge
Inventor: STROHMAIER OTTO
IPC: E06B3/82
Filed: 1987-06-13
Abstract: In the cross-sectional detail of a partition-wall unit shown, a side wall (7), having an angled-off panel part (13), and a wall central part (51), in the form of a door (15) which can be pivoted about a bearing (38) into the position drawn in chain-dotted lines, are fitted together by their side edges. The bearing (38) is fastened, by means of an intermediate moulding (36), on an elevating foot (16) which bears the side wall (7). The two panel units (7) and (15) have interengaging z-shaped side surfaces and thus form in each case a flange (41) and an angle groove (43) for the engagement of the flange of the neighbouring panel. Each panel part exhibits two thin wall shells (24, 25) which overlap one another at the edges, profiled channel elements (47) being additionally introduced. In each case one sealing strip (40) is introduced between flange (41) and angle groove (43). The panel core (43) is enclosed by the panel sheath (23) such that it is outwardly sealed on all sides and is rigid with respect to deformation. At least on the z-shaped side surfaces, each central panel can be used as a door and can be pivoted open from the sealing position. <IMAGE>

Title: Arrangement of a transformer and of a mast in an overhead-line system for electricity transmission
Inventor: PFEIFFER RICHARD DR ING
IPC: H01F27/08
Filed: 1987-09-28
Abstract: So-called mast transformers have, up until now, usually been liquid-cooled and set up on a platform borne by a mast. According to the invention, use is now made of an air-cooled transformer and the above-ground part of the mast is designed as a chimney (8), it being supported on a mast foot (1) via radially arranged spoke-type webs (7), thus forming downwardly open air-inlet ducts beneath the transformer, and the chimney (8) enclosing the transformer and thus safeguarding it against accidental contact. The arrangement according to the invention reliably prevents damage to the environment as a result of escaping oil and facilitates the performance of unavoidable maintenance work on the transformer. The arrangement according to the invention can be used, in particular, in rural districts and in areas where there is only a small supply or little demand for electric energy. <IMAGE>

Patent DE-3817238-A1 (DE)
Title: Heat-insulating panel
Inventor: NEUMANN WERNER
IPC: E04D13/16
Filed: 1988-05-20
Abstract: The fastening of heat-insulating panels (1), which consist of rigid foam, are smooth on the upper side and provided with a corrugated structure on the underside, on a roof covering formed by corrugated panels poses problems as a result of possible damage to the corrugated panels. Adhesive connections between a roof covering of this type and the heat-insulating panels are also not without problems. A heat-insulating panel (1) according to the invention is characterised by a smooth upper side (2) and a corrugated underside (3), the latter being designed for bearing on a roof covering comprising corrugated panels. Located on the upper side (2) of the heat-insulating panel (1) is a row of grooves (13) in which wooden strips (15) are introduced such that they are flush with the upper side (2). The wooden strips (15) serve to receive screws (16) which extend through the material with the heat-insulating panel (1) and through a roof covering and are consequently received directly in the roof substructure, e.g. in the purlins. By virtue of the heat-insulating panels (1) being pressed in a linear manner onto the roof covering, a reliable, in particular statically calculable, fastening of the same is achieved. <IMAGE>

Title: Device for safety and for protection against attacks at doors of houses and flats
Inventor: KANSY HUBERT
IPC: G08B15/02
Filed: 1988-06-04
Abstract: To date, doors of houses and flats were secured against attacks only by means of door chains and the like. When the door is open, these offered only little security and could be easily overcome. Equipped with this novel device, in the moment of danger, when for example the door which is secured by means of a door chain is only slightly open and the petitioner suddenly turns out to be a wrongdoer and, through force, attempts to enter, the wrongdoer can be repulsed by simply pressing the trigger button. By pressing the spray button, irritant gas is sprayed via spray nozzles in the direction of the position of the wrongdoer (door frame) with the purpose of securely reclosing the door. Safety and protection against attacks at doors of houses and flats.
Patent DE-3827890-A1 (DE)
Title: Process and filler for stabilising in particular slopes and surfaces
Inventor: TILLINGHAST JAMES T
IPC: E02D17/20
Filed: 1988-08-17
Abstract: There are proposed a process and a filler for stabilising in particular slopes and surfaces made of a layer of stones and/or boulders. An example of a filler which has been used to date for filling cavities in the stone layer is sand. However, the sand was washed out very rapidly by water so that the stone packing lost its stability. This disadvantage is avoided by a filler composed of a pumpable, soil-type material to which there are added organic colloids, minerals such as clays and clay colloids as well as plants and/or parts of plants as additives. The organic colloids and minerals, which are composed of a mixture of materials which are nonswellable or sparingly swellable and materials which are highly swellable, impart a high primary stability to the slope or the surface due to their swellability in connection with water. Tendrils and roots of the added plants and parts of plants provide a further stabilising effect.

In this arrangement, effects in the manner of a jet pump are to arise.
Patent DE-3837026-A1 (DE)
Title: Balance for high tare loads
Inventor: WOEHRL JOSEF
IPC: G01G23/14
Filed: 1988-10-31
Abstract: The invention relates to a balance for high tare loads having a lever system suitable for the taring, to which a display device is assigned. The essential feature of the invention consists in the fact that, deviating from known taring methods, a system engaging as closely as possible to the balance bridge or directly on the balance bridge is provided for the taring according to the invention. The taring is carried out by means of a tare weight applied on a lever or by means of second weighing system for the tare weight. The advantages achieved with the invention consist especially in that the lever, bearing and knife edge of the lever mechanism are relieved of the high tare weight as far as the weighing-out device, wear and loading of the lever mechanism are reduced, a significantly smaller weighing region is sufficient and the measuring accuracy is improved.
